Using asm.js as an alternative for debugging

For whatever reason, you may feel that debugging using Edge or Opera may be necessary. If you feel that you must debug in a browser that doesn't have a WebAssembly debugger, you could compile for asm.js as an alternative. If so, change the -s WASM=1 flag to -s WASM=0, and you will be set. This will create a JavaScript file instead of a WASM file, but the two files (in theory) should behave the same.
